摘　　要：针对预应力玻璃钢混凝土管(FPCCP)脱模起吊过程中可能出现的3个问题分别从试验、理论、有限元计算3个方面进行了分析研究。结果表明,有限元计算结果与理论计算结果相一致。FPCCP脱模起吊时,A截面的剪切强度、B截面的拉伸强度、过渡层的粘接剪切强度均有非常高的安全储备,脱模起吊过程安全。这为后期的研究及大批量生产提供有价值的参考。Regarding three possible problems in the course of demolding fiberglass prestressed concrete cylinder pipes （ FPCCP ） by lifting, the safety of this operation was studied by testing, theoretical calculation and finite element calculation respectively. The study indicated that the results of finite element calculation and theoretical calculation were identical. In the process of lifting, the shear strength of Section A, the tensile strength of Section B and the bond shear strength of the transition layer all had very high safety reserve so that a safe process of pipe demolding was enabled. This provided a valuable reference for futural research and high volume production of such pipes.
